David Hildenbrand 90b8fab5cd mm/highmem: make nr_free_highpages() return "unsigned long" ...

It looks rather weird that totalhigh_pages() returns an "unsigned long"
but nr_free_highpages() returns an "unsigned int".

Let's return an "unsigned long" from nr_free_highpages() to be consistent.

While at it, use a plain "0" instead of a "0UL" in the !CONFIG_HIGHMEM
totalhigh_pages() implementation, to make these look alike as well.
